Hw 8.87

Postby Virpal Gill 1B » Wed Jan 17, 2018 4:38 pm

Does anyone know how to do this problem using the enthalpy of sublimation instead of separately doing the enthalpy of fusion and enthalpy of vaporization?
The problem is: How much heat is required to convert a 42.30-g block of ice at 5.042 degrees C into water vapor at 150.35 degrees C?

Even though we are not provided the data for the enthalpy of sublimation, this can be found by adding the enthalpy of fusion and the enthalpy of vaporization. However, the calculation would technically be the same as you are still adding the two enthalpies together.
